Unidentified missile platform

During the early reign of the Galactic Empire, the Coruscant Security Force identified Darth Vader's starship as a Separatist splinter cell. With Vader's starship having its communications jammed and thus not being able to transmit access codes to Coruscant's orbital defense, a missile platform launched several missiles, resulting in Vader crashing on Coruscant's surface. The incident was part of a conspiracy against Vader by several Imperial officers.
